TECHNICAL FIELD

The invention relates to a compound useful for the treatment of diseases or conditions associated with P2X receptor, specifically to P2X₃ and/or P2X_(2/3) receptor, and a pharmaceutical composition comprising such compound.

BACKGROUND ART

Adenosine triphosphate (ATP) is known to serve as a source of energy in cells and a substrate of phosphorylation, as well as an extracellular messenger. It is known that ATP is released from a cell by various stimulation such as cellular injury, inflammation, nociceptive stimulus, reduced blood oxygen level, and also known to be released together with another messenger from a primary sensory nerve terminal. ATP thus released mediates various extracellular signal transductions through an ATP receptor (Non-Patent Document 4, Non-Patent Document 5).

ATP receptor is categorized into ionotropic P2X family and G protein-coupled P2Y family. For P2X family, seven subtypes have been reported, and a member of this family forms a homo-trimeric structure or a hetero-trimeric structure together with another member of this subtype and functions as a non-specific cation channel (Non-Patent Document 6).

ATP is known to cause pain, and studies with P2X₃ knockout and knockdown methodologies have shown that P2X₃ receptor mediates transmission of chronic pain. P2X₃ receptors are expressed in a specific manner on peripheral sensory nerve to form a homo-complex or hetero-complex with P2X₂ (P2X_(2/3)) (Non-Patent Document 1).

Later, the compound A-317491 was reported as a specific antagonist to P2X₃ and P2X_(2/3) receptors. A-317491 is tri-substituted-N-[(1S)-1,2,3,4-tetrahydro-1-naphthalenyl]benzamide derivative represented by the formula:

(Patent Document 1). It was reported to exhibit an antagonist activity to P2X₃ and P2X_(2/3) receptors and analgesic action in neuropathic pain model and inflammatory pain model (Non-Patent Document 7). This indicates that pain sensation is transmitted via P2X₃ or P2X_(2/3) receptor and that a compound having a P2X₃ or P2X_(2/3) receptor antagonistic activity is useful as an analgesic. Also, compounds that exhibit P2X₃ or P2X_(2/3) receptor antagonistic activity are described in Patent Documents 2-7.

Additionally, it was recently reported that vesical reflex was strongly reduced in P2X₃ knockout mouse (Non-Patent Document 2), suggesting that a compound having P2X₃ antagonistic activity is useful in the treatment of diseases caused by overactive bladder. Also, compounds that exhibit P2X₃ or P2X_(2/3) receptor antagonistic activity are described in Patent Documents 2-7.

In addition, P2X₃ receptor is expressed in neuroepithelial bodies (NEB) of the lung (Non-Patent Document 9), ATP induces cough (Non-Patent Document 10), and the like, therefore it ie suggested that P2X₃ receptor participates in signal transduction in the respiratory system (Non-Patent Document 11). These reports suggest the possibility that compounds that exhibit P2X₃ receptor antagonistic activity are useful in the treatment of respiratory diseases.

Later, the compound A-317491 known as a specific antagonist to P2X₃ and P2X_(2/3) receptors was reported inhibiting an activity of afferent vagal A fiber in pulmonary diseases (Patent Document WO2006/012639). Additionally, biphenyl and phenyl-pyridine derivatives were reported as a specific antagonist to P2X₃ and P2X_(2/3) receptors, and it is suggested that the biphenyl and phenyl-pyridine derivatives exhibit improving effect on respiratory diseases in asthma and lung model (Patent Document WO2010/149578). Also, compounds that exhibit P2X₃ or P2X_(2/3) receptor antagonistic activity are described in Patent Documents 2-7.

Patent Documents 8-17, and 23 disclose compounds having similar structure to the compounds of the present invention but they do not disclose analgesic effect and P2X₃ or P2X_(2/3) receptor antagonistic activity. Patent Document 18-22 and Non-Patent Document 11 disclose compounds having P2X₃ receptor antagonistic activity but the structures are different with those of the compounds of the present invention.

Test Examples Test Example 1-1 Evaluation of Human P2X₃ Receptor Inhibitory Activity

Stably expressing cell line (C6BU-1 cell transfected with human P2X₃ receptor gene (GenBank accession number Y07683) was used. The cells were seeded in a 96-well microtiter plate at a concentration of 8000 cells/well and cultured in the medium (7.0% fetal bovine serum, 7.0% horse serum, 1% antibiotic and antifungal in DMEM) for one day at 37° C. under 5% carbon dioxide atmosphere. The medium was replaced with 4 μM Fluo-3-AM solution (20 mM HEPES, 137 mM NaCl, 5.27 mM KCl, 0.9 mM MgCl₂, 1.26 mM CaCl₂, 5.6 mM D-glucose, 2.5 mM probenecid, 1% BSA, and 0.08% Pluronic F-127, pH 7.5) and incubated at 37° C. under 5% dioxide carbon atmosphere for one hour. The plate was washed with washing buffer (20 mM HEPES, 137 mM NaCl, 5.27 mM KCl, 0.9 mM MgCl₂, 1.26 mM CaCl₂, 5.6 mM D-glucose, 2.5 mM probenecid, pH7.5), and each well was added with 40 μL of this buffer. The plate was placed in High-Throughput Screening System FDSS 3000 (Hamamatsu Photonics K.K.). Measurement of fluorescence intensity by FDSS 3000 was started, and 40 μL of DMSO solutions containing different concentrations of the test compound as prepared by dilution with dilution buffer (20 mM HEPES, 137 mM NaCl, 5.27 mM KCl, 0.9 mM MgCl₂, 1.26 mM CaCl₂, 5.6 mM D-glucose, 2.5 mM probenecid, 0.1% Pluronic F-127, pH7.5) were dispensed to each well through the built-in automatic dispenser. Five minutes after, 50 nM ATP solution (50 μL) prepared by dilution with the dilution buffer was dispensed through the built-in automatic dispenser, and the measurement of fluorescence intensity was continued for 4 min. For each well, the specific maximum fluorescence intensity was calculated as the ratio of the maximum fluorescence intensity after addition of the ATP solution to the fluorescence intensity at the starting of the measurement. The 50% inhibitory concentration (IC₅₀) was calculated under the assumption that the specific maximum fluorescence intensity without test compound is 0% inhibition and that the specific maximum fluorescence intensity when the dilution buffer was added in place of ATP solution is 100% inhibition, to evaluate the inhibitory activity of the test compound. FDSS software (Hamamatsu Photonics K.K.) was used for calculation of the specific maximum fluorescence intensity. IC₅₀ was calculated using Microsoft Excel (Microsoft Corporation) and XLfit (idbs Ltd.)

Test Example 1-2 Evaluation of Human P2X₃ Receptor Inhibitory Activity

Stably expressing cell line (C6BU-1 cell transfected with human P2X₃ receptor gene (GenBank accession number Y07683) was used. The cells were seeded in a 384-well microtiter plate at a concentration of 3000 cells/well and cultured in the medium (7.0% fetal bovine serum, 7.0% horse serum, 1% antibiotic and antifungal in DMEM) for one day at 37° C. under 5% carbon dioxide atmosphere. The medium was replaced with 4 μM Fluo-3-AM solution (20 mM HEPES, 137 mM NaCl, 5.27 mM KCl, 0.9 mM MgCl₂, 1.26 mM CaCl₂, 5.6 mM D-glucose, 2.5 mM probenecid, 0.5% BSA, and 0.04% Pluronic F-127, pH 7.5) and incubated at 37° C. under 5% dioxide carbon atmosphere for one hour. The plate was washed with washing buffer (20 mM HEPES, 137 mM NaCl, 5.27 mM KCl, 0.9 mM MgCl₂, 1.26 mM CaCl₂, 5.6 mM D-glucose, 2.5 mM probenecid, pH7.5), and each well was added with 20 μL of this buffer. The plate was placed in High-Throughput Screening System FLIPR 384 (Molecular Device Co.). Measurement of fluorescence intensity by FLIPR 384 was started, and 20 μL of DMSO solutions containing different concentrations of the test compound as prepared by dilution with dilution buffer (20 mM HEPES, 137 mM NaCl, 5.27 mM KCl, 0.9 mM MgCl₂, 1.26 mM CaCl₂, 5.6 mM D-glucose, 2.5 mM probenecid, 0.1% Pluronic F-127, pH7.5) were dispensed to each well through the built-in automatic dispenser. Five minutes after, 150 nM ATP solution (25 μL) prepared by dilution with the dilution buffer was dispensed through the built-in automatic dispenser, and the measurement of fluorescence intensity was continued for 4 min. For each well, the specific maximum fluorescence intensity was calculated as the ratio of the maximum fluorescence intensity after addition of the ATP solution to the fluorescence intensity at the starting of the measurement. The 50% inhibitory concentration (IC₅₀) was calculated under the assumption that the specific maximum fluorescence intensity without test compound is 0% inhibition and that the specific maximum fluorescence intensity when the dilution buffer was added in place of ATP solution is 100% inhibition, to evaluate the inhibitory activity of the test compound. The specific maximum fluorescence intensity and IC₅₀ were calculated using Spotfire (Science & Technology Systems, Inc.)

Test Example 2 Evaluation of Rat P2X₃ Receptor Inhibitory Activity

Rat P2X₃ receptor gene (GenBank accession number NM_031075) is expressed in C6BU-1 cell. The C6BU-1 cells are seeded in a 96-well microtiter plate at a concentration of 2500 cells/well and culture in the medium (7.0% fetal bovine serum, 7.0% horse serum, and 1% antibiotic and antifungal in DMEM) for one day at 37° C. under 5% carbon dioxide atmosphere. The plasmid is transfected into the cells using transfection reagent FuGENE6 (Roche). The transfected cells are cultured in the medium for one day at 37° C. under 5% carbon dioxide atmosphere. The medium is replaced with 4 μM Fluo-3-AM solution (pH7.5) containing 20 mM HEPES, 137 mM NaCl, 5.27 mM KCl, 0.9 mM MgCl₂, 1.26 mM CaCl₂, 5.6 mM D-glucose, 2.5 mM probenecid, 1% BSA, and 0.08% Pluronic F-127, and incubates at 37° C. under 5% dioxide carbon atmosphere for one hour. The plate is washed with washing buffer (20 mM HEPES, 137 mM NaCl, 5.27 mM KCl, 0.9 mM MgCl₂, 1.26 mM CaCl₂, 5.6 mM D-glucose, 2.5 mM probenecid, pH7.5), and each well is added with 40 μL of this buffer. The plate is placed in High-Throughput Screening System FDSS 3000 (Hamamatsu Photonics K.K.). Measurement of fluorescence intensity by FDSS 3000 is started, and 40 μL of DMSO solutions containing different concentrations of the test compound as prepared by dilution with dilution buffer (20 mM HEPES, 137 mM NaCl, 5.27 mM KCl, 0.9 mM MgCl₂, 1.26 mM CaCl₂, 5.6 mM D-glucose, 2.5 mM probenecid, 0.1% Pluronic F-127, pH7.5) are dispensed to each well through the built-in automatic dispenser. Five minutes after, 50 nM ATP solution (50 μL) prepared by dilution with the dilution buffer is dispensed through the built-in automatic dispenser, and the measurement of fluorescence intensity is continued for 4 min. For each well, the specific maximum fluorescence intensity is calculated as the ratio of the maximum fluorescence intensity after addition of the ATP solution to the fluorescence intensity at the starting of the measurement. The 50% inhibitory concentration (IC₅₀) is calculated under the assumption that the specific maximum fluorescence intensity without test compound is 0% inhibition and that the specific maximum fluorescence intensity when the dilution buffer is added in place of ATP solution is 100% inhibition, to evaluate the inhibitory activity of the test compound. FDSS software (Hamamatsu Photonics K.K.) is used for calculation of the specific maximum fluorescence intensity. IC₅₀ is calculated using Microsoft Excel (Microsoft Corporation) and XLfit (idbs Ltd.).

Test Example 4 Evaluation of the Urinary Function in a Rat Model of Cystitis Surgery for Cystometry

A rat is fixed in the supine position after being given anesthesia through the inhalation of 2% isoflurane (Anesthetic background; Nitrous oxide:Oxygen=7:3). A midline incision is made in its abdomen to expose the bladder. A cannula (made by processing a polyethylene tube (PE-50: Becton Dickinson)) is inserted through a small incision on top of the bladder and fixed to create a bladder fistula. The other end of the cannula is led through the hypodermal tissue to the back, and the muscular coat and skin are sutured. The cannula, which is led to the back, is protected with a stainless spring in the middle and connected to the cannula swivel.

Acetic Acid Infusion

Two days after the surgery, 0.3% acetic acid is infused into the bladder through the indwelled cannula at a rate of 4 mL/hr for 30 minutes to induce cystitis. The animals, where acetic acid is not infused, are used as normal animals.

Cystometry Measurement

Two or three days after the acetic acid infusion, the other end of the cannula inserted into the bladder is connected to a T shape stopcock and then the intravesical pressure is recorded continuously using a pressure amplifier while infusing warmed normal saline solution at a rate of 3.0 mL/hr from one side and through a pressure transducer on the other side. The baseline of the intravesical pressure is measured (for approximately 40 minutes) after a measurement for stable duration (for approximately 20 minutes). After that, a vehicle, positive control compound or test compound are administered, and the value after administration is measured for approximately 120 minutes. A compound of the present invention is crushed with a mortar and pestle so as to be 0.1-2 mg/mL/kg solution or suspension using 0.5% methylcellulose solution, and administered to an animal orally with an oral sonde. At the same time, the voided urine is received on scales under the cage to measure the variation in weight simultaneously.

Data Adoption Criteria

Based on the voiding interval, normal animals whose voiding interval is 10 minutes or longer were adopted and those whose voiding interval is shorter than that were excluded. In the case of the animals into which acetic acid is infused, those whose voiding interval is less than half the average value of the normal animals are adopted as animals with cystitis and those whose voiding interval is longer than that were excluded.

Collection of Residual Urine

After the completion of the measurement, the infusion of normal saline solution is stopped immediately after urination to collect the residual urine under pentobarbital sodium anesthesia. The collected residual urine is transferred to the voided urine receiver and recorded on the chart.

Test Example 5 Analgesic Effect in a Seltzer Model Preparation of Partial Sciatic Nerve Ligation Model in Rats

Rats were anaesthetized using isoflurane/02 inhalation anaesthesia. After induction of anesthesia, the left thigh was shaved. An incision was made in the skin just below the hip bone. The muscle was bluntly dissected to expose the sciatic nerve. One third (⅓) to one half (½) of the sciatic nerve thickness was tightly ligated and the wound was closed. The right thigh is used as a sham-operated control. The right thigh undergoes an identical procedure with the left hind limb, however, the sciatic nerve is not manipulated or ligated.

Evaluation (1)

Two weeks after nerve ligation, the effect on mechanical allodynia is assessed using a series of von Frey filaments. For habituation, the rats are placed into a plastic cage on a wire mesh bottom. The mechanical sensitivity (mechanical threshold) of the hind paws is estimated with a series of von Frey filaments (0.4-26 g). The measurement of mechanical sensitivity of the right and left hind paws is performed to obtain predose mechanical sensitivity. The rats showing the threshold change from 0.6 to 2 g (in nerve ligated side) and 8 to 15 g (in sham operated side) are used in the experiments. On the day before the experiment, the rats are evaluated with a series of von Frey filaments to familiarize them with the test procedure. The adopted animal is administrated with the test compounds. The test compounds are homogenized with mortar and pestle and suspended or diluted in 0.5% Methyl Cellulose to prepare 0.03-30 mg/2 mL/kg suspension and orally administered to rat using a syringe attached with a sonde. Post-dose mechanical sensitivities of the right and left hind paws are measured at approximately 1 to 5 hours after drug administration. Percent reversal of mechanical allodynia for each rat is calculated using the following formula. The analgesic effects of the compounds are compared.
